The short answer was yes, but here’s the key quote from Silver (emphasis ours):

“I’ve been pleased with what I’ve seen with his arm in terms of the short and intermediate stuff. But if you talk to Broncos higher-ups they’ll say, ‘We’re not totally sure he can air it out.’ Sure you can get by on short and intermediate tosses for most of your quarterbacking existence, but I think the problem is if opposing defensive coordinators start to suspect that he can’t beat you deep maybe they pack it in and he starts getting the Chad Pennington treatment.”
